Etymology In the name of Borna scholars have seen similarity with the name of Saxons count Bernus (father of Gottschalk of Orbais), and Burgundian names Bornus, Borno and Bornonus. Petar Skok, besides supporting possibility of being a Frankish name (''borns'' meaning "son"), also proposed Slavic etymology from Proto-Slavic *''born-'' which with liquid metathesis could be related to Slavic personal names Branimir, Branislav and others. History Borna is documented in the "Royal Frankish Annals" (''Annales regni Francorum''). He is first mentioned regardin ...

Abbasid Caliphate
The Abbasid Caliphate or Abbasid Empire (; ) was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. After overthrowing the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH), they ruled as caliphs based in modern-day Iraq, with Baghdad being their capital for most of their history.

Baghdad became the center of science, culture, arts, and invention in what became known as the Golden Age of Islam.
